My invention relates to cosmetics, and more specifically to an improved compact of the type used for dispensing rouge and face powder.

6 The particular embodiment of the process selected for illustration includes the formation of a stiff paste; the fabrication of a com act of substantially the size of the finished article; and the desiccation ofthe fin- 10 ished compact.

According to one illustrative procedure, I take 99 pounds of domestic talc free from silica and mica, 9 pounds of heavy imported chalk, and ounces of yellow ochre. These 15 ingredients are mixed in a powder mill and sifted through a rapid sifter to remove grit. The resulting dry material is then ground into a stiff aste in a mixer. In the mixer I add one iundred cubic centimeters of a fatty-natured emollient, a proper amount of perfume oil to suit the taste of the user, and twelve hundred cubic centimeters of binder to each eighteen pounds of dry material. One emollient I have used is purified water-white mineral oil having a specific gravity of 0.868. In addition to the foregoing, sufficient water is included to make a heavy paste of the whole. The binder is an intimate mixture of water-and powdered gum arabic in the ratio of twenty grams of gum arabic to one gallon of water.

The paste ingredients are ground in the mixer for from one-half to three-quarters of an hour and molded into compacts of substantially the exact size and shape of the finished product. In the molding operation I form pellets of the paste, each pellet containing a very slight excess of material above that necessaryto form the finished compact. A suitable metal plate, with its upper surface slightly roughened, is coated with a non-shrinking and non-absorbing glue and the pellet dropped on the glue. A suitable stamping die is then em oyed to form the ellet, andthe fabricated compact is ready or desiccation. v

The drying process normally involves standin for about three days-in a gentle draft 0 ordinary atmospheric air. -At the end ofthe drying process the slight top crust accumulating during drying is re-. moved, as b li ht sand-papering, and the finished pro uct is ready for the user. i

The pigment carrying medium in the fin- .not more than, 6% of the total solids by Application filed December 4, 1926. Serial No. 152,722.

ished compact is both plastic to such an extent that the jolting or possible flexure of the supporting plate encountered in ordinary use' of the compact will not chip or break it; and sufficiently friable to be capable of use with substantially the same effect as loose powder.

Without further elaboration, the foregoing will so fully explain the gist of my invention, that others may, by applying currentknowledge, readily adapt it for use under various conditions'of service. Moreover, it is not essential that all the different parts of the invention be employed in conjunction, as certain \of them may be advantageously made use of in various combinations and subcombinations.

What I claim is: I

1 A compact containing the following ingredients in the following original proportions; a. color vehicle, a mineral oil and a binder, in the proportions of 18# of color vehicle to 100 cc. of mineral oil to 1200 cc. of binder, said binder containing originally 20 grams of powdered gum 'arabic to one gallon of water; said color vehicle comprising domestic talc free from silica, heavy imi ported chalk, and yellow ochre in the proportions of 99# tale to 9# .chalk and 15 oz. yellow ochre.

2. A compact containing the following ingredients in. the followmg original proportions; a color vehicle, a mineral oil and a inder, in the proportions of 18# of color vehicle to 100 cc. of mineral oil, and 1200 cc. of binder, said binder containing origin'ally 20 grams of powdered gum arabic to: one gallon of water; said color vehicle comprising domestic talc free from silica, and heavy imported chalk, in the proportions of 99# tale to 9# chalk, and a pigment.

3. A wet-formed compact comprising a color vehicle, a fatty-natured emollient, and

a binder, the. fatty-natured emollient being weight. 7

4. A wet-formed compact comprising a color vehicle a fatty-natured emollient,

and a hinder, the fatty-natured emollient being not more than 6% of the total solids by weight, and the binder com risin water 1 and a solid not exceeding 2% y we1ght of the total solids.

5. A wet-formed compact comprising a emollient amounting to 5 the total solids.

6. A wet-fbrmed 'compact containing a color vehicle, and a fatty-natured" emollient in the proportion of substantially 99% Vehlr.

' cle and 1% emollient.

7. A wet-formed compact containing a color vehicle, afatty-natured emollient, and

a binder, the fatty-natured emollient not ex ceeding 6% of the total solids by weight, and the binder beingfuflicient in quantity to produce cohesion su stantially equal to that produced by powdered gum arabic not exceeding 2% of the total solids by weight. 8. A wet-formed compact containing -a color vehicle an'd a mineral oil, in the prop irtion of substantially 99% vehicle and 1% 01 Y 9. A wet-formed compact, comprising a binder, a body having substantially the composition resulting from the 1 admixture 'of' ninety-nine pounds of talc with from nine to sixteen pounds of chalk, and substantially one per cent of a fatty-natured emollient.

In testimony whereof; I havesigned -m name to this specification.
